In what direction is mechatronics heading?

　　 Mechatronics is an interdisciplinary field that integrates mechanics, electronics, optics, control systems, computing, and information technology. Its development and advancement depend on, and in turn drive, the progress of related technologies. Therefore, the main directions of mechatronics development are as follows:

　　 Intelligentization

Intelligentization is a major direction in the development of mechatronics technology in the 21st century. Research on artificial intelligence in mechatronic systems is receiving increasing attention, with intelligent robotics and CNC machine tools representing key applications. Here, “intelligentization” refers to the characterization of machine behavior: building upon control theory while integrating new ideas and methodologies from artificial intelligence, operations research, computer science, fuzzy mathematics, psychology, physiology, and chaos dynamics to emulate human intelligence, endowing machines with capabilities such as judgment and reasoning, logical thinking, and autonomous decision-making, thereby achieving higher-level control objectives. Admittedly, it is neither feasible nor necessary for mechatronic products to possess intelligence that is entirely identical to that of humans. However, high-performance, high-speed microprocessors make it both entirely feasible and essential to equip mechatronic products with low-level intelligence or with certain aspects of human-like intelligence.

　　 Modularization

Modularization is a significant yet challenging undertaking. Given the vast diversity of mechatronic products and the multitude of manufacturers, developing standardized mechatronic modules—featuring uniform mechanical, electrical, power, and environmental interfaces—is an exceedingly complex but critically important task. Examples include power units that integrate speed reduction, intelligent speed control, and electric motors; control units equipped with vision, image-processing, recognition, and ranging capabilities; and various mechanical devices capable of performing typical operational functions. Such standardized modules enable rapid new-product development while also facilitating production scaling. Achieving this requires the establishment of comprehensive standards to ensure compatibility and seamless interfacing among components and modules. Although conflicts of interest currently make it difficult to formulate international or national standards in this area, such standards can gradually emerge through the consolidation of major enterprises. Clearly, the benefits derived from the standardization and serialization of electrical products are well established: for both companies that manufacture standardized mechatronic modules and those that produce complete mechatronic systems, scale-up will usher in a promising future for the mechatronics industry.

　　 Networking

In the 1990s, the most prominent achievement in computer technology and related fields was the emergence of networking technology. The rise and rapid development of networking have brought about profound transformations across science and technology, industrial production, politics, the military, education, and everyday life. Various networks have integrated the global economy and production on a scale never seen before, while competition among enterprises has also become increasingly globalized. Once a new mechatronic product is developed, as long as it offers unique functionality and reliable quality, it can quickly achieve strong sales worldwide. With the widespread adoption of networks, network-based remote control and monitoring technologies are flourishing, and the terminal devices used for such remote control are themselves mechatronic products. Fieldbus and local-area-network technologies have made the networking of household appliances an inevitable trend; by leveraging home networks (homenets), various household appliances can be interconnected to form computer-centered, computer-integrated appliance systems (CIAS), enabling people to enjoy the convenience and pleasure brought by advanced technologies right in their own homes. Therefore, it is clear that mechatronic products are inexorably moving toward greater networking.

　　 Miniaturization

Miniaturization emerged in the late 1980s and refers to the trend of mechatronics advancing into the realm of micro-machines and microscopic systems. Abroad, this field is known as Micro-Electro-Mechanical Systems (MEMS), which broadly encompasses mechatronic products with geometric dimensions not exceeding 1 cm³ and is now extending into the micrometer- and nanometer-scale regimes. MEMS devices are characterized by their small size, low power consumption, and high maneuverability, giving them unparalleled advantages in biomedicine, defense, information technology, and other fields. The primary bottleneck in the development of MEMS lies in micro-machining technology; the fabrication of MEMS components relies on precision manufacturing techniques, specifically ultra-precision technologies, which include lithography and etching.

　　 Greening

The development of industry has brought about profound changes in people’s lives. On the one hand, material abundance and greater comfort have become commonplace; on the other hand, resource depletion and severe environmental pollution have emerged as pressing concerns. Consequently, there is growing calls for the protection of environmental resources and a return to nature. It is against this backdrop that the concept of “green products” has arisen, reflecting green transformation as a defining trend of our times. Green products are designed, manufactured, used, and disposed of in ways that meet stringent environmental protection and human health standards, causing little or no harm to the ecosystem while maximizing resource efficiency. The design of green mechatronic products holds tremendous potential for future development. In essence, the greening of mechatronic products means that they do not pollute the environment during use and can be recycled and reused at the end of their life cycle.

　　 Systematization

One of the hallmark features of systematization is the further adoption of open, standardized bus architectures in system design. This enables flexible system configuration, allowing for arbitrary customization and combination while striving to achieve coordinated control and integrated management among multiple subsystems. Another key feature is the substantial enhancement of communication capabilities: in addition to RS-232, systems typically also support RS-485 and DCS interfaces, reflecting a trend toward greater personalization. Looking ahead, mechatronics will place even greater emphasis on the relationship between products and people; this “personalization” of mechatronic systems has two dimensions. First, since the ultimate users of mechatronic products are humans, it is increasingly important to imbue these products with human-like intelligence, emotion, and humanity—particularly in the case of household robots, where the ultimate goal is seamless human–machine integration. Second, mechatronic systems are increasingly inspired by biological mechanisms, leading to the development of a wide range of bio-inspired mechatronic products. In fact, many existing mechatronic products have been designed with direct inspiration drawn from animals.
